From the metro station, you go up the stairs to Euclid Street.
Cross the street and take either one of the two busses: the Union-Garden, line 13 (which
will take you to the main gate of the Missouri Botanical Garden Ridgway Center) or
the “Kingshighway”, line 95, which will leave you on South Kingshighway Boulevard
and Shaw, at about two blocks from the Monsanto Center (Vandeventer and Shaw).
